Hovering Ring Magnets

Magnets appear to hover. Ask students to predict what will happen. Stack like poles facing so upper rings float apart. Key idea: Like magnetic poles repel and the guide prevents sideways motion. Ask: What is holding the magnet up? Safety and cleanup: Large magnets only; keep away from mouths. https://www.google.com/search?q=%22Hovering+Ring+Magnets%22+science+demonstration+experiment
